A Gargoyle is a spout in the form of a grotesque human or animal figure projecting from a roof gutter to throw rainwater clear of a building (definition courtesy of Merriam-Webster online dictionary). This one lives on the cathedral in Ulm, Germany.
I was showing my students the concept that the value of a color (how light or dark the hue is) does all the work in showing the form of an object. The color itself lends an emotional impact, but as one can see here, any color may be used. In this example I have used New Gamboge for the yellow, Permanent Alizarin Crimson for the red, and French Ultramarine for the blue.
